Why am I so scared to talk to my crush?? How to break the ice?

[joshpeckfreak]

Ok so im 20 and my crush is 26...I REALLLY like him lol. My name is Hannah and his name is Justin and we live two very different lifestyles. He lives in LA and I live in Georgia lol. He is a upcoming musician(i already know the backstory on that so no explanations :]) and I'm just a regular poor country girl, but without the country accent lol.. I have talked to him on the phone once..but my voice started going really high and I couldn't say anything but yeah, cool, okay. And also..I live with my family, and they are always in my business. I can't shut the door to my room, I cannot go in the bathroom. I can only stay outside for so long. The first time Justin did call me..they started asking questions. And I can't ever have any privacy. And I had to lie and say it was one of my school friends. I mean...I can talk to him on Facebook like its nothing lol..which is weird. And also, I know he likes me cause he's always telling me that he loves me, calls me dollface, he even told me I should come to L.A. I was on a call with him the other day and I had to hang up randomly and I had to lie and say I ran out of minutes..I'm tired of having to run around. So can anyone give me some nice advice or something about overcoming my fear? Don't be mean. Thanks
I mean...he has a girlfriend...so he can't possible really reject me lol..i guess? And...I live in a Conservative, Christian household, so according to my family I AM allowed to talk to whoever I want..but they question me about it so I choose not too..I met him thru Facebook.
He flirts with all girls lol. And well how can I break him out of my life?
